The crypto space has been growing immensely since Bitcoin\u2019s inception in 2009, and it is not without problems. Apart from the (apparently) overly technical nature of blockchains to the general public, the safety of invested money has been a problem encountered by the space. Despite efforts from centralized entities (such as CEXs) and multi-sig wallets to enhance crypto security, there have been instances of hacks and misplaced private keys, putting investors\u2019 crypto savings in danger. Also, being overly centralized (in the case of exchange savings) and overly decentralized (in the case of personal crypto wallets) has not been helpful to investors in many ways despite promising to be so.<\/p>\n

Is there a solution to this problem? A process called MPC wallet development says so, as it uses one of the long-known elements in the cryptography space \u2013 Multi-Party Computation. If you are thinking about how Web3 and a classic cryptographical concept can work together, this comprehensive guide can help you to get a clear understanding of how it all happens. These applications might help the Web3 space not to lose cryptocurrencies permanently, unlike the US$100 billion worth of Bitcoin lost forever due to wallet mismanagement and crypto exchange platform exploits.<\/p>\n

What is an MPC Wallet?<\/span><\/h2>\n

An MPC (Multi-Party Computation) wallet is a crypto wallet application<\/a><\/strong> that uses a combination of advanced cryptography and distributed computing technologies to safeguard a wallet\u2019s private keys. For those who are new to the crypto space, the private key in a crypto wallet helps to process transactions (similar to a credit card PIN), while the public key is the wallet\u2019s address (similar to the bank account number).<\/p>\n

Developing an MPC wallet can be advantageous as it depends on multiple parties to hold its private keys as \u201cshares\u201d who do not need to reveal their keys to each other. For a crypto transaction to be processed from the wallet, a certain number of shares should be combined.<\/p>\n

Technological Aspects of an MPC Wallet<\/span><\/h2>\n

Blockchains<\/span><\/h3>\n

Similar to any other Web3 application, blockchains play a crucial role in MPC wallet development. Apart from being the bases for crypto transactions, they also help in processing them by assisting other technologies. They helped in creating new-age cryptographical concepts such as threshold signatures and Multi-Party Computation, which have a huge role in crypto wallet apps.<\/p>\n

Threshold Signature Scheme (TSS)<\/span><\/h3>\n

Threshold Signatures play a major part while developing your MPC wallet. TSS, the scheme behind these signatures, helps to generate a single digital signature from multiple signers before processing a transaction. This is where Multi-Party Computation comes into play, as it helps to evaluate the private keys digitally in a distributed manner.<\/p>\n

Multi-Party Computation (MPC)<\/span><\/h3>\n

Multi-Party Computation (MPC) refers to the process of using inputs from different people without revealing them to compute the output. In the case of a wallet application, inputs correspond to shares of the private key, and the output corresponds to the ultimate private key to process a transaction. The following elements are vital for any MPC process:<\/p>\n
